Hi,
I also do not understand we should we register to the onsip website.........but I finally decided to do it to get the document. I found it really user-perspective convenient and therefore many starting users will highly appreciate it as a getting started document.
I just have a few comments:
1) in 1.2.3 Transactions, Dialogs and Sessions: SIP transactions: you should mention that retransmissions are also part of a transaction.
2) In 1.4: Understanding SIP and RTP: RTPC will not always use RTP port +1. Newer versions of SDP standards include a parameter to indicate the port of RTCP and therefore ALWAYS is not 100% certain (although almost always it will be true).
3) In 1.7 URI, R-URI, Branches: URI stands for Uniform Resource Identifier and not Uniform Resource Identificator. Request URI is not the URI present in the To: header field but the one present in the first line of the SIP request.
I hope this remarks are right,
Samuel.
